replace a line in a file

[TehOne]

I need to replace a line in a file, example test.file:

cat test.file

DBAN 196157 5419883235 364173045 932 43933467 4915 256 21538970 4291 288 12197694 2809 1044 14041695 2782 95 4526567 488 0 0 0 75 7120403 1678 43
CDALA 196157 5419883235 364173045 932 43933467 4915 256 21538970 4291 288 12197694 2809 1044 14041695 2782 95 4526567 488 0 0 0 75 7120403 1678 43
CSI 196157 5419883235 364173045 932 43933467 4915 256 21538970 4291 288 12197694 2809 1044 14041695 2782 95 4526567 488 0 0 0 75 7120403 1678 43

I'd have to replace always the second number from a specific line in a file, like:

grep CDALA test.file | awk '{print $3}

and then replace it with for example 2425212475 so the file would be:

cat test.file

CDALA 196157 2425212475 364173045 932 43933467 4915 256 21538970 4291 288 12197694 2809 1044 14041695 2782 95 4526567 488 0 0 0 75 7120403 1678 43

try this:

grep CDALA <filename> | awk '{sub ($3, "2425212475");print}'

man awk
